<hr><a name="details"></a><h2>Detailed Description</h2>
<p> The TQTextDrag class is a drag and drop object for
transferring plain and Unicode text.
<p>
<p> Plain text is passed in a <a href="tqstring.html">TQString</a> which may contain multiple lines
(i.e. may contain newline characters). The drag target will receive
the newlines according to the runtime environment, e.g. LF on Unix,
and CRLF on Windows.
<p> TQt provides no built-in mechanism for delivering only a single-line.
<p> For more information about drag and drop, see the <a href="tqdragobject.html">TQDragObject</a> class
and the <a href="dnd.html">drag and drop documentation</a>.
<p>See also <a href="draganddrop.html">Drag And Drop Classes</a>.
<hr><h2>Member Function Documentation</h2>
<h3 class=fn><a name="TQTextDrag"></a>TQTextDrag::TQTextDrag ( const <a href="tqstring.html">TQString</a> & text, <a href="tqwidget.html">TQWidget</a> * dragSource = 0, const char * name = 0 )
</h3>
Constructs a text drag object and sets its data to <em>text</em>. <em>dragSource</em> must be the drag source; <em>name</em> is the object name.
<h3 class=fn><a name="TQTextDrag-2"></a>TQTextDrag::TQTextDrag ( <a href="tqwidget.html">TQWidget</a> * dragSource = 0, const char * name = 0 )
</h3>
Constructs a default text drag object. <em>dragSource</em> must be the
drag source; <em>name</em> is the object name.
<h3 class=fn><a name="~TQTextDrag"></a>TQTextDrag::~TQTextDrag ()
</h3>
Destroys the text drag object and frees up all allocated
resources.
<h3 class=fn>bool <a name="canDecode"></a>TQTextDrag::canDecode ( const <a href="tqmimesource.html">TQMimeSource</a> * e )<tt> [static]</tt>
</h3>
Returns TRUE if the information in <em>e</em> can be decoded into a
<a href="tqstring.html">TQString</a>; otherwise returns FALSE.
<p> <p>See also <a href="#decode">decode</a>().
<p>Example: <a href="simple_dd-example.html#x2827">iconview/simple_dd/main.cpp</a>.
<h3 class=fn>bool <a name="decode"></a>TQTextDrag::decode ( const <a href="tqmimesource.html">TQMimeSource</a> * e, <a href="tqstring.html">TQString</a> & str )<tt> [static]</tt>
</h3>
Attempts to decode the dropped information in <em>e</em> into <em>str</em>.
Returns TRUE if successful; otherwise returns FALSE.
<p> <p>See also <a href="#canDecode">canDecode</a>().
<p>Example: <a href="simple_dd-example.html#x2828">iconview/simple_dd/main.cpp</a>.
<h3 class=fn>bool <a name="decode-2"></a>TQTextDrag::decode ( const <a href="tqmimesource.html">TQMimeSource</a> * e, <a href="tqstring.html">TQString</a> & str, <a href="tqcstring.html">TQCString</a> & subtype )<tt> [static]</tt>
</h3>
This is an overloaded member function, provided for convenience. It behaves essentially like the above function.
<p> Attempts to decode the dropped information in <em>e</em> into <em>str</em>.
Returns TRUE if successful; otherwise returns FALSE. If <em>subtype</em>
is null, any text subtype is accepted; otherwise only the
specified <em>subtype</em> is accepted.
<p> <p>See also <a href="#canDecode">canDecode</a>().
<h3 class=fn>void <a name="setSubtype"></a>TQTextDrag::setSubtype ( const <a href="tqcstring.html">TQCString</a> & st )<tt> [virtual]</tt>
</h3>
Sets the MIME subtype of the text being dragged to <em>st</em>. The
default subtype is "plain", so the default MIME type of the text
is "text/plain". You might use this to declare that the text is
"text/html" by calling <a href="#setSubtype">setSubtype</a>("html").
<h3 class=fn>void <a name="setText"></a>TQTextDrag::setText ( const <a href="tqstring.html">TQString</a> & text )<tt> [virtual]</tt>
</h3>
Sets the text to be dragged to <em>text</em>. You will need to call this
if you did not pass the text during construction.
